DIBELS 8th Edition

HILL experts have trained hundreds of educators to use DIBELS to improve literacy instruction, as part of our School Wide Transformation projects, and as part of the Reading First initiative in Massachusetts.

This one-day workshop will overview DIBELS 8th Edition, developed by the Center on Teaching and Learning at the University of Oregon. DIBELS 8th Edition is a battery of short (one minute) fluency measures that can be used for universal screening, benchmark assessment, and progress monitoring in Kindergarten through 8th grade. DIBELS 8th Edition is more useful for more students in more grades than ever before. For title 1 schools, special education programs, students identified with dyslexia, and anyone focused on improving literacy for all students, DIBELS 8th Edition is the least invasive, and one of the most effective screening tools available. When you choose DIBELS 8th Edition as your assessment solution, you are trusting scientific evidence, research-based practices, and decades of experience in teaching and learning.


DIBELS 8th Edition discontinues a few old DIBELS subtests, revises other existing subtests, and introduces a new subtest:

  • Letter Naming Fluency (LNF) now accounts for how frequently letters appear in both upper- and lower-case forms.
  • Phonemic Segmentation Fluency (PSF) now accounts for both word frequency and the number of phonemes in a word.
  • Nonsense Word Fluency (NWF) now accounts for the frequency of spelling patterns.
  • Word Reading Fluency (WRF) is now part of the DIBELS assessment system.
  • Oral Reading Fluency (ORF) only requires one passage per benchmark period and passages are now written by experienced authors.
  • Maze passages are now written by experienced authors and include several other improvements.
